| Abstract Scope |
Magnetic topological phases of quantum matter are an emerging frontier in physics and material science, of which kagome magnets appear as a highly promising platform. We explore magnetic correlations in the recently identified topological kagome system TbMn6Sn6 using muSR, combined with local field analysis and neutron diffraction. Our studies identify an out-of-plane ferrimagnetic structure with slow magnetic fluctuations which exhibit a critical slowing down below T*C1 ≅ 120 K and finally freeze into static patches with ideal out-of-plane order below TC1 ≅ 20 K. The appearance of the static patches sets in at a similar temperature as the appearance of topological transport behaviors. We further show that a hydrostatic pressure of 2.1 GPa stabilizes the topological ferrimagnetic ground state, giving rise to a magnetically-induced topological system whose magnetism can be controlled through external control parameters.
